Tamiya F103GT Rear Upper Deck Plate Graphite - F103GT-21/SG by 3Racing  [F103GT-21/SG]

Rear deck summary

This graphite rear upper deck plate is made for the Tamiya F103GT chassis and carries the part number F103GT-21/SG. The component is an RC hop-up intended to change torsional stiffness at the rear of the chassis so you can tune handling and balance on 1/10 GT-style circuits.

The plate replaces the factory rear upper deck and uses the F103GT's original mounting points, so fitment is straightforward with standard hardware. Graphite offers higher stiffness than common plastic decks, reducing unwanted flex under lateral loads while keeping weight low for competitive RC models.

Use this plate when you want to explore chassis tuning through structural changes rather than swapping suspension parts. Expect shifts in rear traction and transient response as the stiffer deck alters load transfer during cornering and acceleration in race setups.
